Description copied from interface: ParserContext

Create an Abstract Syntax ExpressionInOCL containing the parsed expression on behalf of a potential owner.

This an invariant/precondition may specify its constraint as the owner
an operation body may specify the operation as the owner

The owner should be non-null but a null value is tolerated for deprecated compatibility.

Specified by:
